Ñurrently, clover is one of the most perspective agricultural crop. It is
grown for green fodder, hay, silage, haylage, for the preparation of grass
meal, pellets and briquettes.

For clover, as well as other perennial grasses, adaptive activity of Albit
is important, such as increase the ability of plants to endure different stresses
(wintering, drought, mowing). Because of this, clover is one of the most responsive
culture to the biostimulant - average yield increase of green
mass under the influence of Albit in the field trials was 36%.

According to the results of field trials conducted on clover, VNNII Agricultural Chemistry
RAAS recommends using Albit on clover to enhance growth and formative
processes, enhance the regrowth after bevelling, increase
the number of inflorescences, acceleration of development growth phases,
enhance resistance to unfavorable environmental factors, enhance stability
to diseases, increase yields of green mass, improve product quality.

We give examples of field trials on clover.

Evaluation of the efficacy of Albit on clover was carried out in SPK "Tarbaevo" Suzdal’
district Vladimir region (2006), where the treatment was carried out in field
trial on vegetation in the phase of stem at rate consumption 50 mL/ha. It was
obtained increase yield of green mass - 7% due to Albit treatment.

In Research Institute of Fodder (Brno suburb, Czech Republic, 2012) it was
examined the effect of Albit on clover meadow. It has been shown that when
using 60 mL/ton Albit for presowing seed treatment and 40 mL/ha Albit for spraying
crops, yield increase of clover meadow vs. control was 14.2% (the sum of all
mowing).

In field trials VNIIZR (Voronezh region, Ramon district, 2008) it was conducted
two-fold spraying of crops of clover variety Trubetchinskylocal during
vegetation period. Both treatments with Albit (in phase regrowth of plants
and in the beginning of budding) had a significant positive impact on growth
and development of plants. It was shown significant influence of biostimulant
on the formation generative organs. At the same time, the greatest effect (quantity
of knotted buds) was observed when using Albit at consumption rate 0.04 L/ha
(174.8% vs. control). Due to increasing the height of the stems (by 10.7-27.4%)
and their weight (by 40.7-57.3%) compared to control, crop of green mass of
culture significantly increased. Harvest of green mass of clover under the
influence of Albit in all variants has grown by about 40% (by 43.3% with Albit
using after first mowing, 40.4% - after second mowing). In general, based on
the amount of mowing, double treatment with Albit allowed to obtain from 144
to 183 additional centners of green mass per hectare with an average yield
in the control 450 centner/ha.

Also, the biostimulant Albit, providing the immunizing effect on clover, showed
a high enough protective effect against wide range of clover diseases. It was
found that the maximum immuno-inducing effect of biostimulant against a pathogens
was showed in the double treatment of clover with Albit in consumption rate
0.04 L/ha. At this dose biostimulant restrained development all studied clover diseases:
powdery mildew, ascochyta-leaf spot, brown patch, and, in particular, anthracnose
and rust (biological efficiency 92.2 and 72.7%, respectively). In the case
of rust, fungicidal effect of drug was clearly visible in the early manifestation
of the disease, as well as on the background of increasing of the infectious
process in June.

With increasing consumption rate of biostimulant up to 70-100 mL/ha, the speed
of development of the generative organs was increased, resulting in increase
the quantity of pink buds about 2 times (it is important for seed crops). However,
when study various consumption rates of Albit, it was concluded that based
on many indicators of stimulating, protective and economic effect, the optimal
dose is 40 mL/ha (FGNU VNIIZR MSKh RF, 2008).

The pure income when using Albit in the field trial was
21678 rubles/ha, recoupment of costs when adding of biostimulant - 9.5 times.

Based on results of conducted field trial, the following method of
using biostimulant is considered optimal for clover: sprayings of
plants at the beginning of the resumption of vegetation (after overwintering),
second - in the phase of stem - the beginning of budding (or after mowing
grass). The ratio of the treatments - 2. The consumption rate - 40 mL/ha
at consumption rate of working fluid - 300 L/ha.
